我正在使用 videoView 播放视频,但出现致命信号 6 错误,因此我得到了使用 textureview 而不是 videoview 的解决方案,但我不知道如何使用它。这是我的代码。

public class MainActivity extends Activity {
    ListView listview;
    CustomListAdapter adapter;
    private static ProgressDialog progressDialog;
    public static int currentItem;
    public static ArrayList<String> videoLIst;
    public static MediaController mediaController ;
    boolean pauseOnScroll = true;
    boolean pauseOnFling = true;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_view);
        System.gc();

        videoLIst = new ArrayList<String>();
         mediaController = new MediaController(MainActivity.this); 
        videoLIst.add("http://journey.coderspreview.com/uploads/Home_Video/mov_bbb.mp4");
        videoLIst.add("http://journey.coderspreview.com/uploads/experience/165/video/father-and-young-daughter.mp4");
        videoLIst.add("http://journey.coderspreview.com/uploads/experience/185/video/couple-on-sail-boat.mp4");
        videoLIst.add("http://journey.coderspreview.com/uploads/experience/39/video/VID-20141231-WA0006.mp4");
        videoLIst.add("http://journey.coderspreview.com/uploads/experience/26/video/VID-20141216-WA0004.mp4");
        listview = (ListView) findViewById(R.id.list);
        listview.setAdapter(new CustomListAdapter(this, videoLIst));
         listview.setRecyclerListener(new RecyclerListener() {
                @Override
                public void onMovedToScrapHeap(View view) {
                    VideoView videoView = (VideoView)view.findViewById(R.id.VideoView);

                }
            });
      listview.setOnScrollListener(new AbsListView.OnScrollListener() {
          private int mFirstVisibleRow = -1;
          private int mActiveItem = -1;

          @Override
          public void onScrollStateChanged(AbsListView view, int scrollState) {
          }


          @Override
          public void onScroll(AbsListView view, int firstVisibleItem,
                               int visibleItemCount, int totalItemCount) {
              int firstVisibleRow = listview.getFirstVisiblePosition();
              if( mFirstVisibleRow != firstVisibleRow )
              {
                  mFirstVisibleRow = firstVisibleRow;

                  // Cancel the video of the previous active item
                  VideoView prevActiveVideoView = getVideoViewForRow(mActiveItem);
                  if( prevActiveVideoView != null )
                  {
                      prevActiveVideoView.pause();
                  }

                  // Start the video of the new active item
                  mActiveItem = mFirstVisibleRow + 1;
                  VideoView newActiveVideoView = getVideoViewForRow(mActiveItem);
                  if(newActiveVideoView != null)
                  {
                      newActiveVideoView.start();

                  }
              }
          }

          private VideoView getVideoViewForRow(int row)
          {
              int firstVisibleRow = listview.getFirstVisiblePosition();
              View rowView = listview.getChildAt(row-firstVisibleRow);
              return (rowView == null) ? null : (VideoView)rowView.findViewById(R.id.VideoView);
          }

      });

}

活动视图.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >

    <ListView
        android:id="@+id/list"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:divider="@color/list_divider"
        android:dividerHeight="1dp"
        android:listSelector="@drawable/list_row_selector" />

</RelativeLayout>

video_list_item.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <VideoView
        android:id="@+id/VideoView"
        android:layout_width="match_parent"
        android:layout_height="100dp" />
 <ProgressBar 
        android:id="@+id/progress"
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:layout_gravity="center"
        />
    <TextView
        android:id="@+id/txvposition"
        android:layout_width="match_parent"
        android:layout_height="80dp" />

</LinearLayout>

我正面临这两个问题。1)在滚动视频/列表项开始为已经缓冲的项目再次缓冲。2)在快速滚动列表变得太迟钝,卡住和崩溃。

请指导我如何使用textureview insted of videoview。
